Title: Improvements in magnetic tape sound recording and reproducing apparatus
IPC: G11B15/50
Filed: 1950-08-29
Abstract: 688,412. Magnetic sound recording and reproducing apparatus. BRYANS, J. R., STEARNS, C. E., and SCOTT, P. B. Aug. 27, 1951 [Aug. 29, 1950], No. 21322/50. Class 40 (ii) [Also in Group XXIV] The take-up reel 13 for a magnetic tape recorder is driven from a motor 15 either at a high speed through friction gearing 21, 20 and a clutch 18 or at a lower speed through gearing 22, 23, 31 and a flange 32 on the reel. The lower speed is adjusted by moving the wheel 31 and its shaft 33 axially by means of an eccentric 38 controlled by a knob 39. A solenoid (71)-operated brake acts on the flange 32. A storage spool 14 is driven tor rewinding by a motor 16. The apparatus is controlled by a switch which has movable contacts 52 ... 56 and fixed contacts 57 ... 68 which are fed with the full voltage from a transformer T, except for the contacts 65 ... 67 which are supplied with about half the voltage from a tap 69. In the " off " position of the switch with the moving contacts in their left-hand position, the motor 15 is supplied with the full voltage and the motor 16 is supplied with the reduced voltage to keep the tape taut, and the solenoids 30, 27, 71 are de-energized. On the next position of the switch, " recording and reproducing," a torque is still applied to the reel 14 by the motor 16 to keep the tape taut, and solenoids 30 and 71 are energized to force the wheel 31 up into engagement with the flange 32 to drive the reel 13 at an adjustable speed, and to release the brake. In the next position of the switch " fast forward " the solenoid 30 is de-energized, while the solenoid 27 is energized to force the gear 20 into engagement with the clutch 18 and drive the reel 13 at high speed. In the fourth, " re-wind," position of the switch the solenoid 27 is de-energized while the motor 16 is supplied with the full voltage and the motor 15 is not energized. In a modification, Figs. 4 and 5 (not shown), the storage spool 14 is driven through. a belt and pulleys from the shaft 24 and a solenoid-operated, magnetic clutch on the spool shaft, which clutch allows reduced torque to be applied to the spool, except during rewinding. Two guide rollers are provided between the spools (Fig. 2, not shown).

Abstract: 597,383. Treating wood with liquids. PHILLIPS, B. J., and LATEGAN, P. N. Aug. 21, 1945, No. 21402. Convention date, Oct. 10, 1944. [Class 140] Timber is compressed to reduce its volume and then impregnated with a polar liquid so as to restore it substantially to its original volume, the compression not going beyond the critical point at which the structure of the wood becomes too deteriorated to enable its volume to be restored. The polar liquids have a high dielectric constant and cause swelling when absorbed, those specified being water, glycerine, and water solutions of phenol formaldehyde resins. Preferably, the wood is compressed in the fibre saturated condition, then dried without resinification and finally impregnated. Compression in a direction transverse to the grain and also to the larger direction of the timber is preferred. Vacuum treatment may follow the compression and precede the impregnation.

Patent GB-215792-A (GB)
Abstract: 215,792. Freund, B. May 12, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Tell-tale apparatus. - In an arrangement for signaling electrically the variations of strength of an electric current, particularly applicable to copying telegraphy, the signals are transmitted as secondary current impulses derived from the primary current at definite intervals of time, and the time incidence. or the duration of each such impulse is a measure of the strength of the primary current at the moment of derivation. Fig. 5 shows one arrangement for copying telegraphy. The primary circuit includes a photo-electric cell 14, controlled by light passing through the image on the transmitting cylinder 12, and a mirror galvanometer 5 disposed within a rotating cylindrical shutter 7 with evenly-spaced openings 8. The light reflected from the mirror passes through the successive openings 8 and is focused by a lens 9 on a photoelectric cell 2 in the secondary circuit. The impulses thus produced in the secondary circuit are of equal strength but are each retarded by an interval of time which is proportional to the deflexion a of the reflected ray and is thus a measure of the increase in strength of the primary current. In a modified transmitter the shutter 7 and lens 9 are dispensed with and the cell 2 is carried by a disc which is rotated to expose the cell periodically to the reflected ray. In a further modification the cylinder 7 is replaced by a rotary disc disposed in a plane at right angles to the plane of the deflected rays and provided with evenly spaced oblique slots. The impulses in the secondary circuit, amplified if necessary, are transmitted by wire or wirelessly to a chord galvanometer 26 at the receiving station, and the deflection of the chord 'by each impulse is such as to uncover a bundle of rays of angle #. This bundle is intercepted by a shutter 29 rotated synchronously with the shutter 7 and provided with openings 30 equal in number to the openings 8 and equal in width to the portions 31 of the shutter wall between the openings. The phase is such that one such portion 31 covers the bundle of rays at the moment when one of the openings 8 passes the line 6' of zero deflection of the ray reflected by the mirror at the transmitting station, and the retardation of each impulse thus results in a corresponding length of an opening 30 subtending the bundle of rays at the moment when the chord is deflected. The light is focused by a lens 32 on a light-sensitive surface. on a cylinder 33 rotated synchronously with the cylinder 12. In a modified transmitter, Figs. 8 and 10, employing a mirror galvanometer 5, the cylinder 7 is replaced by a rotary disc 47 disposed in a plane at right angles to the plane of the deflected rays and provided with evenly spaced triangular openings 48.
